Questions and Answers for TP-LINK Smart Wi-Fi Light Switch with 3-Way Kit

A:  If your bulb supports dimming you will be able to turn on the light. Once the light is on you can control how bright the bulb is.

A:  The device has a built in dimmer slide switch, just like a toggle on/off switch that has a slide dimmer. Just remember, if you have Incandescent no problem. If you have LED or CFL Light Bulbs, they'll need to be dimmable bulbs.

A:  I just installed a pair of these smart switches but didn't see any reference in the instructions (App based) to it being used as a dimmer. I believe its only function is on/off.

A:  The switch connects to your Wi-Fi system. There are several ways in which you can communicate with the switch. Through your Phone app and the Alexa and Google home systems. Once connected you can open the app or speak to Google and or Alexa and tell the switch to turn on or off or tell the dimmer switch to set at whatever percentage you desire of light intensity. For example you can say “Hey Google set my dimmer to 50% “ or “Alexa set my dimmer to 50%” Or you can just open your app and control it from the Phone.

A:  Generally, if your phone can connect to the interner then you can control your device

A:  Hi Bill, There is a free App that you can download into to your phone and then you can use the app to control the lighting (on/off, dimming.). Hope that helps, Travis

A:  b) You must install a dimmer (https://www.homedepot.com/p/TP-LINK-Smart-Wi-Fi-Light-Switch-Dimmer-HS220/304847707) for this to be able to dim. Most of the other people answering are wrong.

A:  Yes

A:  Yes the switch does work as single pole and the app works as well. I found a conversation on the TP Link support site stating that they will not guarantee that this will consistently work since it was not designed for single pole use. https://community.tp-link.com/us/home/forum/topic/151795?page=1&t=2019%2F01%2F02%2016%3A26%3A06%20%2B0000

A:  Yes

A:  By reviewing other people's answers to this question I would like to mention right away one thing: This question is incomplete in the first place. If the question refers to a "dimming" ability with "three way functionality" then at least one SMART THREE-WAY switch and one SMART-DIMMER switch are required. If the question refers to only a "three way functionality" then only one SMART THREE-WAY switch is needed. And finally, if question refers to only a "dimming" ability then only one SMART-DIMMER switch is required. Again, prior to installing any of the above scenarios it is highly recommended to get very well familiarized with the wiring diagram. Also, before going into a great ENDEAVOR of messing with your current in-walls existing wiring, it is highly recommended to build a quick short-wired and completely well visible test scheme on a kitchen table and test-play with it first insuring that your knowledge of the proper wiring is absolutely impeccable. And then one shell take on the final real installation project.

A:  No, one smart switch and the other can the dummy 3 way that's from TP-Link

A:  My guess is that a smart switch must be used on both switches in a 3-way circuit to have full functionality of both switches. That being said, I would think if you had one smart switch and a std switch that is ALWAYS left on, it would work. I am a DIYer so please correct me if I'm in error.

A:  I know it is designed to be in a pair. I used them separately and it works well. For me I just wanted the lights to be on and off using the app. The only issue is if you use the other manual switch to turn on the lights it will NOT show up in the app. If you use only the app it will work fine. The switches will turn on the lights but the switch must not tell the app the lights are on. I hope that helps.

A:  The kit includes two 3-way wifi switches but you can choose to use only one of the wifi switches with the other being the normal 3-way switch. To use the wifi switches, you need to be able to connect the neutral wire of the new switch to a neutral in your switch junction box, otherwise the wifi switch won't work at all. I replaced both of my old 3-ways with the new wifi 3-way switches but it might have been smarter to just use one old and one new wifi and save the second wifi switch for another light.

A:  It is recommended that you use a smart switch for both sides of the three-way as well as the four-way. This gives you a more secure connection to the Wi-Fi and the switches communicate with one another as well. This will help produce a more stable connection and a more consistent experience with the smart home set up. However, I do have several three-way switches in which I am only using one smart switch. It is important that the traveler wires are connected correctly and that the smart switch is connected to the common wire. I have not had a problem with any of my three-way switches using just one smart switch.

A:  No, there is nothing that I could find that states this unit could be used in a circuit with a dimmer.

A:  These switches are not designed to work with or as a dimmer. TP-Link has a dimmer that I own and it works fantastic. This particular smart light is design to pair with its partner.

A:  This switch is a dimmer.

A:  Its works as a 3 way switch. I can't answer if it would work on a 4 way however.

A:  This product is designed as a 3 way switch.

A:  I think you can use these on both. From what I read, you only need to replace 1 of the current 3-way switches (whether it be a 3-way or 4-way setup). I actually also used this HS210 model as a 2-way switch.

A:  Yes, on a three way.

A:  Yes, this is a 3way switch. Not 4way.

A:  Yes it requires a neutral. Most smart devices require a neutral.

A:  Yes, it does require a neutral wire to work.

A:  Yes, the wifi transceiver won't work without a neutral return wire as it draws its power from the hot lead but needs the neutral to complete the circuit.

A:  Yes, this model requires a neutral.

A:  Yes, it does require a neutral wire to work.
